CANNES, France — The stars of the Turkish film "Winter's Sleep" are showing their solidarity for those affected by the mining tragedy in that country as they promote the film in Cannes.

The actors and director held up signs with the hashtag Soma during their photo call Friday for the movie.

Soma is the Turkish city where at least 284 people were killed in a fire in a coal mine, the country's worst mining accident. There has been an outcry of anger and protests from the public, some of whom blame the government for not taking action to correct alleged safety problems in Turkey's mines.

"Winter's Sleep," by director Nuri Blige Ceylan, is a family drama starring Haluk Bilginer, Demet Akbag and Melisa Sozen. All four held the signs for photographers on Friday.
